    The name means "coyote" after a similar-sized predator that inhabits today the same regions. It was found in Utah and found to be related to Utahraptor, a contemporary. Because of it I immediatly thought, what if it's just a juvenile Utahraptor? But the article mentions that its bones seem like those of a fully grown adult.

    For some weird reason the paper talks about giant raptors like Utahraptor and Achillobator, but they say that dromaeosaur size ranged from mockingbird to emu. (Aren´t emus very small compared to Utahraptor? :confused:)

    Also, it seems that the caudotheca of dromaeosaurs became reduced when they became larger, to allow greater tail flexibility and better maneuverability while running and turning at high speed.
